중등도 이상 활동성 류마티스관절염 성인을 위한 표적 치료 플랫폼 연구

Rheumatoid arthritis (RA) is a chronic inflammatory disease that primarily affects the joints, causing pain, swelling, stiffness, and loss of function. Synovial fibroblasts play a key role in RA pathogenesis, with treatment-refractory patients demonstrating increased numbers of these cells. The goal of this study is to evaluate the safety and effectiveness of ABBV-2294 (a combination of ABBV-722 and upadacitinib) compared to each drug alone in treating moderately to severely active RA. The platform study will measure improvements in disease activity using the American College of Rheumatology (ACR) criteria, changes in disease activity scores, and quality of life measures. ABBV-2294 is an investigational combination drug being developed for the treatment of moderately to severely active rheumatoid arthritis. This is a Phase 2b, randomized, double-blind platform study. In sub-study 1, participants are placed in 1 of 5 groups, called treatment arms. Each group receives a different treatment consisting of either ABBV-722 alone, upadacitinib alone, or various doses of ABBV-722 combined with upadacitinib. Adult participants with a diagnosis of moderately to severely active rheumatoid arthritis who have failed at least 1 prior biologic disease-modifying antirheumatic drug (bDMARD) will be enrolled. Around 250 participants will be enrolled in the study at multiple sites worldwide. Participants will receive oral tablet doses of ABBV-2294 (combination of ABBV-722 and upadacitinib), ABBV-722 alone, or upadacitinib alone. The study comprises a 24-week Double-Blind Phase (Period 1) followed by an optional 52-week Blinded Long Term Extension Phase (Period 2), for a total treatment duration of up to 76 weeks. After completing treatment, participants will have a 30-day Follow-Up Period. There may be higher treatment burden for participants in this trial compared to their standard of care due to study procedures. Participants will attend regular visits during the study at a hospital or clinic, including screening, baseline, and scheduled visits through Week 76, followed by a follow-up visit. The effects of the treatment will be checked by medical assessments, blood tests, checking for side effects, and completing questionnaires.
